75 Many statewide models are "highway only" in the sense that the models only simulate highway modes of transportation. Therefore, the mode choice section of the Guidebook must also include guidance on transferability and a set of transferable auto occupancy rates.

auto Occupancy and Mode Choice parameters 77 2010 Travel Survey of Residents of Canada Table 6.5 provides information on party size of long-distance trips by purpose according to the previously referenced TSRC. Not surprisingly, the majority of business trips have a party size of one person (81.16 percent)

auto Occupancy and Mode Choice parameters 79 of Long-Distance Multimodal Passenger Travel Modal Choice Model, that may provide calibrated model parameters. Therefore, the key transferable parameter for the mode choice step is the auto occupancy rate, used to convert person trips to vehicle trips for highway assignment.
